Function:

Whether you're talking about movies or videogames, "3D" is a process that feeds the left eye and the right eye different views in order to artificially trigger the mind's perception that the objects being viewed are real objects, not simple images.

The Call of Duty: Black Ops II Gaming Glasses work much like some of the 3D glasses popularly used in movie theaters and provide a realistic 3D experience without additional weight from electronics or the need for batteries.

Performance:

There are many different ways to deliver different views to the left and right eyes, and they differ in effectiveness as well as functional complexity.

Call of Duty: Black Ops II 3D Gaming Glasses feature polarized lenses - one lens is polarized horizontally and the other is polarized vertically. This allows unwanted views to be cancelled out, letting the left eye see just what the left eye is supposed to and the right eye see just what the right eye is supposed to, creating the 3D effect.

I am familiar with this method of creating a 3D display, from movie theaters utilizing two projectors each having a polarized lens. However, I was completely baffled when I saw this method being used with an LG 3D television at the Call of Duty: Black Ops II review event. It worked beautifully, but how the television screen had interleaved images shown polarized along two different axes are beyond me.

But, yes, as I said, they did the job admirably. The 3D effect was great and was especially fun to use for the Zombies gameplay.

I also used the Call of Duty: Black Ops II 3D Gaming Glasses at my local Rave Motion Pictures theater to watch Wreck-It Ralph in 3D. The film used RealD technology, which is a polarization-based system, and the Call of Duty: Black Ops II 3D Gaming Glasses worked wonderfully. If you'd like to stroll into your local theater in style, now you can bring your own stylish Black Ops II glasses when you go to see the latest 3D flick. (Like a bouse.)

Drawbacks & Problems::

Not everyone can appreciate 3D visuals. For example, 3D movies and gaming causes nausea, eyestrain and headaches for Psibabe. She can't enjoy 3D movies in theaters either, however, so it's not specific to the Call of Duty: Black Ops II Gaming Glasses. If you have had good experiences with polarized lens-based 3D movies in theaters, you will probably be able to utilize the Call of Duty: Black Ops II Gaming Glasses.

Note, however, that the Call of Duty: Black Ops II Gaming Glasses only work with 3D displays that use polarized light to separate the signals. You would need a 3D television that uses this method of 3D to be able to see the 3D visuals. These glasses won't work with shutter-based 3D telvisions or monitors, nor will they work with televisions or monitors that are not 3D-enabled.

You can, however, use the Call of Duty: Black Ops II Gaming Glassesat the theater for many of the 3D movies show in public movie theaters, such as RealD. Your best bet is to go ahead and pick up the provided glasses, just in case the system isn't compatible, but try out your Call of Duty: Black Ops II Gaming Glasses, first and you may be able to enjoy the movie in style.
